I'm happy with FF3.
- The intelligent address bar is nice. I can see it eventually making bookmarks obsolete
- The new bookmark maanger is great. On mac I missed the ability to drag/drop reorganize my bookmarks, I'm glad its back.
- Bookmarks, thanks to the address bar history - and now the intelligent address bar -, are now only really needed for those pages I only visit like once a month, like you know to pay bills, and really I don't WANT a bookmark for those pages...
